Koreader help please

Runnerbeen · 06-03-2025, 02:03 PM

Hi

I have installed KO Reader on my Boox Go Color 7. I was wondering if there is a way to remove the thin black border from the book cover thumbnails in mosaic view please?

Also I have some cbz files. The book covers for all of these files are smaller than the epubs I have uploaded. I’ve tried to replace the book cover with a custom image but the file picker directs me to a data/data/org.koreader.launcher folder which I don’t have access to upload anything to.

Thank you in advance.

Not sure about your first question. (May be possible with a user patch, but not in the UI settings.)

Regarding the folder access: strangely, I also can't navigate to my Android home folder /storage/emulated/0/ on my phone if it starts in the system directory. However, as a workaround (if you haven't done so already, anyway), when you're in the File browser looking at your book files, set that folder as your Home folder (Plus button, Set as HOME folder). Then, when you want to set your custom cover, tap the Home symbol to go to your book folder, and from there you should be able to navigate to your other freely accessible folders on your device.

Thank you for the tip. I’ve followed the steps but when I click on the home icon I get taken to a screen with the message ‘long press file’s name to choose it’ but there is nothing else on the screen ie no folders or files to select. Thank you

Sorry ignore me. I’ve copied a jpg to the home folder and have been able to select that as a replacement cover. Thank you!

In case you didn't know: ↑../ (first line) is to go one level up, from where you can select your other folders.
